Well, if what you want is to simply KNOW what & where he surfed, try these:
1-Check in the history folder in windows explorer. there you can see what
web sites he visited he did that day, yesterday, the day before, etc.
2- And/or also, check the 'cookies' in "my computer' area to see where he
went. websites leave those in this area (C:\documents and settings\his user
account'\cookies)
I mean, these are ways to "check' on your kid to see what they have viewed.
there are ways to see stuff that they may not know that you know how to. You
can also check your recent documents folder that lists the most rececntly
used (MRU) folders, by going to
3-C:\Documents and Settings\his user account' (Recent documents folder is a
hidden file. so, note that you will not find the recent documents folder
unless you 'show' hidden files. Go to tools in window explorer>folder
options>click on the view tab> scroll down to the folder named 'Hidden files
and folders' & click to show hidden files and folders>then click apply>ok .
Now search for the recent documents folder in #3. open and look all you
want. It should show lost of things he viewed recently.
also, try the 'spy' type programs the others recommend. these are just ways
to see stuff.
good luck
